Common Desktop Environment: Style Guide and Certification Checklist

Primary and Secondary Panes

The primary pane should contain the core or base functionality required by nearly all end-users of the application. The primary pane is a standard Motif container that is the main component of the window or dialog. Only the primary pane is visible when the expandable window is initially displayed. An "expand button" allows the user to display a secondary pane providing access to the full functionality of the window or dialog. (See Figure 7-2.)
